The papers in this book are not intended in any way to be professional treatises. They must be viewed in the light of entertaining conversations. Their possible value lies in their directness of impulse, and not in weight of argument. I could not wish to go into the qualities of art more deeply. A reaction, to be pleasant, must be simple. This is the apology I have to offer: Reactions, then, through direct impulse, and not essays by means of stiffened analysis.
